To compare the diagnostic yields and complication rates of transthoracic fine needle aspiration cytology(FNAC) and gun biopsy in the diagnosis of pulmonary mass, a retrospective review was performed in 125 cases. Under the fluoroscopic guide, FNAC was performed by 20G Chiba needle in 91 cases, core biopsy was done by 18.5 G vaccum needle attached with automated biopsy gun in 74 cases and both procedures were done together in 37 cases. Overall sensitivity was 88.4% in FNAC and 87.5% in gun biopsy. For malignant pulmonary tumors, correct type correlation with final diagnosis was obtained in 33(76.7%) out of 43 cases by FNAC and 30(75.0%) out of 40 cases by gun biopsy. For benign pulmonary lesions, there were correct type correlation in 14(35.0%) out of 40 cases by FNAC and 14(53.8%) out of 26 cases by gun biopsy. The complication was pneumothorax and hemoptysis. Pneumothorax occured in 11.1% of FNAC, 10.9% of gun biopsy and 10.9% of both technique, among which chest tube drainages were necessary in one patient by gun biopsy and in three patients by both technique. Although no significant difference of diagnositc accuracy and complication rate was found between FNAC and gun biopsy, gun biopsy was more helpful in the diagnosis of pulmonary benign lesions than FNAC.

The incidence of Mycobacterium kansasii pulmonary diseases are on the increase in Korea with the higher probability of occurrence in middle-aged and older men with underlying lung diseases Among nontuberculosus mycobacterial (NTM) infections, the clinical features of M. kansasii pulmonary infection are most similar to those of tuberculosis (TB). The chest radiographic findings of M. kansasii infection are almost indistinguishable from those of M. tuberculosis (predominance of an upper lobe infiltration and cavitary lesions), even though some suggest that cavities are more commonly thin-walled and have less surrounding infiltration than those of typical TB lesions. Although there are reports on the rare manifestations of M. kansasii infections, such as endobronchial ulcer, arthritis, empyema, cutaneous and mediastinal lymphadenitis, cellulites and osteomyelitis, the association with bronchial anthracofibrosis has not yet been reported. This report describes the first case of M. kansasii infection presenting as a lung mass in the right lower lobe with accompanying bronchial anthracofibrosis.

We have experienced a case of pulmonary adenocarcinoma looked like cavitary lesion of pulmonary tuberculosis in 49-year-old male patient. He has taken antituberculous medication for 5 months under the impression of pulmonary tuberculosis with cavity at local hospital. The cavitary lesion was changed nodular mass on follow-up chest X-ray. Transthoracic fine needle aspiration was done and cytologic specimen suggested squamous cell carcinoma. Right middle lobectomy was performed. The nodular mass, which was confirmed as adenocarcinoma on microscopic examination, had central cavity filled with hemorrhage.

Background: The pulmonary function test is the most basic test method to diagnosis lung disease. The purpose of this study was to research the correlation of the body mass index (BMI), the fat percentage of the body mass (fat%), the muscle mass, the fat-free mass (FFM) and the fat-free mass index (FFMI), waist-hip ratio (WHR), on the forced expiratory volume curve. Methods: Between March and April 2009, a total of 291 subjects were enrolled. There were 152 men and 139 female (mean age, $46.3{\pm}9.92$ years), and they were measured for the following: forced vital capacity (FVC), forced expiratory volume at 1 second ($FEV_1$), and forced expiratory flow during the middle half of the FVC ($FEF_{25-75}$) from the forced expiratory volume curve by the spirometry, and the body composition by the bioelectrical impedance method. Correlation and a multiple linear regression, between the body composition and pulmonary function, were used. Results: BMI and fat% had no correlation with FVC, $FEV_1$ in male, but FFMI showed a positive correlation. In contrast, BMI and fat% had correlation with FVC, $FEV_1$ in female, but FFMI showed no correlation. Both male and female, FVC and $FEV_1$ had a negative correlation with WHR (male, FVC r=-0.327, $FEV_1$ r=-0.36; p<0.05; female, FVC r=-0.175, $FEV_1$ r=-0.213; p<0.05). In a multiple linear regression of considering the body composition of the total group, FVC explained FFM, BMI, and FFMI in order ($r^2$=0.579, 0.657, 0.663). $FEV_1$ was explained only fat% ($r^2$=0.011), and $FEF_{25-75}$ was explained muscle mass, FFMI, FFM ($r^2$=0.126, 0.138, 0.148). Conclusion: The BMI, fat%, muscle mass, FFM, FFMI, WHR have significant association with pulmonary function but $r^2$ (adjusted coefficient of determination) were not high enough for explaining lung function.

A dog with anorexia, cough, and regurgitation was referred to clinic. Diagnostic imaging revealed a solitary mass involving the right cranial and middle lung lobes, compression of the cranial vena cava, and deviation of the heart and mediastinum toward the left side because the mass. The mass was diagnosed as a squamous cell carcinoma via fine needle aspiration. Ten days later, the tumor was larger and the clinical signs were more severe. A combination of piroxicam and itraconazole was administered to control the mass. Two weeks after initiating this treatment, the tumor size decreased and the clinical signs improved significantly.

We report here an unusual case of pericardial tuberculoma that was misdiagnosed as thymic carcinoma on an imaging study. A 48-year-old woman was referred for evaluation of an anterior mediastinal mass. Computed tomography (CT) scans of the chest displayed cystic masses mimicking thymic carcinoma at the anterior mediastinum. Pericardiotomy and surgical drainage of the cystic masses were done, and pathologic examination of the excised pericardial specimen showed a chronic granulomatous inflammation with necrosis, compatible with tuberculosis. Acid-fast bacilli were also identified in the specimen. After treatment with anti-tuberculosis drugs and steroids, the patient showed clinical improvement. Although tuberculous pericarditis usually presents as pericardial effusion or constrictive pericarditis, it can also present as a pericardial mass mimicking thymic carcinoma on CT. Therefore, we suggest that tuberculous pericardial abscess should be included in the differential diagnosis of a mediastinal mass in Korea, with intermediate tuberculosis prevalence.

Pulmonary sequestration is a very rare congenital malfomation, especially when it is located in the infradiaphragmatic retroperitoneal space. The patient was a 56-year-old man with no respiratory symptom but had some postprandial epigastric discomfort for several days. Plain chest x-ray revealed mild elevation of left diaphragm and abdominal CT scan showed large cystic retroperitoneal mass with some calcification. We performed the operation through the thorachoabdominal incision and the mass was proven to be a pulmonary sequestration. Therefore, we report the case with review of literatures.

Pulmonary arteriovenous fistula is a congenital vascular malformation originated from abnormalities of capillary development. Fistulas may develop only in the lung or may be associated with similar abnormalities of the skin, mucous membrane, and the other organs. It may occur with hereditary hemorrhagic telangietasia[Rendu-Osier-Weber syndrome]. Recently we have experienced a case of the pulmonary arteriovenous fistula associated with Schwannoma in 20 year old male man. Tennis ball sized bright reddish mass which was composed of variable sized vascular channels filled with blood clots was located in the just subpleural portion of left lower lobe. Left lower lobectomy was done. Microscopic findings showed variable sized numerous blood vessels embedding in the parenchyma. There was a thumb-tip sized brown nodular mass which was turned out to be Schwannoma at the left 7th thoracic paravertebral area.

Pulmonary arteriovenous fistula is unusually congenital malformation consisting of an abnormal connection between a pulmonary artery and vein. It may appear as an isolated anomaly or with hereditary hemorrhagic telangiectasis. In the classic form, symptoms and signs are caused by the abnormal right to left shunt. since severe clinical symptoms such as paradoxical embolism, infection, and spontaneous rupture with massive bleeding may occur, surgical treatment is often indicated. Recently we have experienced a surgical treatment of pulmonary arteriovenous fistula in 54 years old housewife. She was admitted in May 1986 with recurrent hemoptysis for 1 month. On admission, the PaO2 was 65.2 mmHg without specific findings. Pulmonary arteriovenous fistula was confirmed by preoperative pulmonary arteriography. A well circumscribed cystic mass was noted in visceral subpleural and inferior lingular segment of left upper lobe. Left upper lobectomy was performed with good results. Histologically angiomatous dilatation of abnormal vessels embedded in lung parenchyma was noted. Postoperative PaO2 was 90 mmHg. Postoperative results were good.
